3 Claims.

This invention relates to an improvement in oil wiping machines of the character intended for use in connection with large metal plates to which oil or other suitable liquid is applied to retard corrosive action and the surplus oil is wiped off the surfaces of the plate.

The object of the invention is to provide a machine of this character wherein a uniform distribution of the oil is had on both faces of the plate and the operation of supplying the oil and removing the excess takes place speedily and effectively.

} More particularly, the invention contemplates the provision of a plurality of rollers between which the plate is fed and which apply a coating or film of oil to both surfaces of the plate and the provision of wiping means which removes the excess oil from the plate.

In the accompanying drawings, wherein an go embodiment of the invention is shown, Fig. 1 is a side elevation of the improved machine; Fig. 2 is a vertical sectional view through the machine, and Fig. 3 is a detail view, with parts in section, of the means for adjusting the upper oil-distributing rollers.

The machine includes a frame, one side member of which is shown at H) and the similar op-,

posite side member at H, said members being suitably connected by cross braces, some of which are indicated at Ma. The frame elements just mentioned, carry a bracket l2 in which is journalled a lower, driven, feed roller |3 which cooperates with an upper adjustable sectional type feed roller H to feed a metal plate, diagrammatically indicated at |5 in'Fig. 2 in the direction of the arrow IS in that figure. An adjusting means indicated at I! is provided for bringing the upper roller H to or from the lower roller l3. A plate fed to the rollers l3 and 4, either by hand or by conveying means, passes between the rollers and is fed thereby toward the right in Fig. 2 over the supporting rolls l8 mounted in the bracket l2. While moving over the rolls |8 the plate is heated by suitable heating means such as the gas burners indicated at l9, located below the plate; Said burgers are located in a suitable casing 2|! which extends under and above the moving plate and confines the heat around the plate.

In its travel to the right in Fig. 2, the plate next passes between the two feed rollers 2| and 22, the lower roller 22 being a driven roller as hereinafter explained, and the upper roller 2| being a sectional roller adjustable to and from roller 55 22 by the adjusting screw 23. After passing be- 1937, Serial No. 159,730

tween the feed rollers 2| and 22, the plate is next moved between the oil-applying rollers 24 and 25. The lower oil-applying roller indicated at 24 rotates clockwisely and applies a layer or film of oil to the underside of the plate l5, receiving its supply of oil directly from the oil tray 26 supported between the sides It and II of the frame. A wiping 'roller 21 governs the amount of oil delivered by the oil-applying roller 24 to the underside of the plate, said wiping roller being adjustable to and from the face of the roller 24 by suitable adjusting means controlled by manipulation of the hand wheel 21:: on screw 28.

The upper oil-applying roller 25, rotating in a direction opposite to that of roller 24, receives a supply of oil from the tray 29 supported on the frame, the oil being taken therefrom by feed roller 30 which applies a film of oil to the roller 3| which, in turn, applies oil to the face of the oil-applying roller 25 that applies it to the upper face of the plate l5. The two rollers 30 and 3| are adjustable as a unit to or from the oil-applying roller 25, the adjusting means to accomplish this being shown in detail in Fig. 3. Frame members Ill and II are slotted as indicated at 32 and each slot accommodates a block 320, said block being under the pressure of a coil spring 33 which tends to thrust it toward the right. Rotatably mounted in the portion 34 of the block is the shaft 35 on which the roller 3| is mounted. Shaft 36 on which roller 3|! is mounted, is carried in member 38 adjustable in slot 39 formed in the block 320. The coil spring 40 tends to thrust member 38 to the right. The right end of slot 39 is closed by a plate 4| through which an adjusting screw 42 is threaded, said screw operating against block 38 to move it to any required extent to the left in slot 33 and against the tension of spring 4|. Such movement of the members 38 (one of which. is located at each end of the shaft 36) under pressure of the screws 42 will move the shaft 35 and the roller 30 carried by it to or from the roller 3| as may be required.

Each of the adjusting screws 42 extends through a sleeve 43 threaded in a plate 44 secured on the frame, and the outer end of the adjusting screws each terminate in the hand wheel 45 by which the screw may be manipulated. Sleeve 43 carries at its free end a hand wheel 46 by which it may be rotated independently of the adjusting screw 42. The opposite end of the sleeve 43 is formed with a head 45' rotatable in a plate 46' secured over plate 4|. By rotation of hand wheel 48, the sleeve 43 will be turned in plate 44 so that the block 32 and all of the elements carried by it may be moved as a unit either toward or away from the oilapplying rollers, and particularly to and from the upper roller 25. By manipulation of the hand wheel 45, member ll may be moved so that the adjustment of roller I. to or from roller ll can be had. Thus, by the arrangement disclosed, the amount of oil supplied to the oilapplying roller 25 may be easily controlled and the application of a uniform film of oil to the plate be accomplished.

Oil is supplied to the upper oil tray Ilflby means of the supply pipe ll leading from a tank or other source of supply. Tray 2. is provided with an overflow pipe 48 from which a drip pipe ll extends, said drip pipe leading to the lower oil tray 2 into which it directs any excess oil from tray as. Tray 26 has an overflow pipe 5. connecting to pipe 8| which extends to a suitable pump which feeds all excess oil received by it back into the supply tank from which the feed pipe 41 extends. Through the arrangement disclosed, a constant level of oil in the two trays 28 and a is assured.

The upper oil-applying roller 25 is adjustable to or from the lower roller 24 by suitable means including the adjustment screw 52, terminating in the hand wheel I! for controlling the movement of the upper roller toward the lower one.

When the metal plate passes between the rollers 2 and 25, both sides of the plate simultaneously receive the coating or film of oil from these rollers and then plate II passes between the two rollers 54 and I! which remove excess oil from the surfaces of the plate and also feed the plate onto the conveyor belt 58 (Fig. 2) which carries it away from the machine. The driving means for the various rollers will now be described.

At 51 is an electric motor, the shaft of which carries a pulley is over which the belt '60 extends. Said belt also extends over the pulley 6| secured on shaft 62 journalled in the side frames l and II of the machine. Shaft 82 carries a gear 63 (shown in dotted lines in Fig. 2) said gear meshing with a gear 64 on stud shaft 65, the gear 64 driving gear 66 on the lower oil-applying roller 24. The gear 68 meshes with a gear is secured on the shaft on which the wiping roller 21 is mounted. Gear 63 meshes with a gear 6! on a stud shaft 10, said gear I driving gear ll located on the shaft on which the roller 54 is mounted. Gear ll meshes with a gear I2 on the shaft on which the roller 55 is mounted.

The gear 69 meshes with and drives the gear 13 on a shaft ll journalled between the sides of the frame and on which a pulley 15 1s secured, the belt conveyor extending about said pulley and connecting with a similar pulley at a remote point.

The upper oil-applying roller 25 is driven by the gear 66 on the lower roller 2|, said gear 6' meshing with agear 11 secured on the roller 25. Gear 11 meshes with a gear I! on shaft 35 on which the roller II is mounted, and gear I9 meshes with a gear 80 on the shaft 35 on which roller 30 is mounted. Gear 66 also drives a gear II on a stud shaft '2, said gear ll meshing with a gear 83 on shaft It on which the feed roller 22 is mounted. Also secured on shaft .4 is a sprocket over which a chain bl extends, said chain extending around a sprocket on the shaft 06 on which the feed roller II is mounted. Located within each of the rollers 24 and II is a burner ll to heat these rollers. Through the drive arrangement shown, the plate is fed through the rollers; receives a coating or him of oil on both of its faces from the rollers 24 and 2!, and has the surplus oil removed by the rollers 54 and 55 and is then delivered by the conveyor 56 to any desired remote point.

Briefly, the operation of the machine is as follows:

The plates to be oil-treated are fed to the rollers I3 and I at the left end of the machine, either manually or by conveyor, and the. plate so fed passes over the burners ll and is heated thereby. Feed rollers 22 and 23 next feed it to the oil-applying rollers 24 and 2' from which both surfaces of the plate simultaneously receive a coating or film of oil. between the rollers 54 and I which remove surplus'oil from both sides of the plate. Conveyor 56 then receives the plate and carries it away.
